To all whom it may concern: r

Be it known that. I, CALVIN. B. PA'roI-i, a citizenof the United States,residing, at Glenellyn, in the county of Dupage and State of Illinois,have invented a certain new and useful: Improvement in Roller'SideBearings for Railway-Cars, of whichthe following is av full, clear,concise, and' e'xact description, reference being'had to theaccompanying drawings, forming. a part of this specification.

This invention relates to improvements in roller side bearings forrailway cars.

The object of the invention is to provide a rockably mounted roller sidebearing. for railway cars of simple, cheap and efficient construction. T

In the drawing forming a part of this specification Figure 1 is a sideelevation of the truck and body bolster of a. carshowing my improvementsin connection therewith- Fig; 2 is a top plan yiew of the improvedroller side bearing. Fig. 3 is a vertical sectional View takensubstantially on the line 33 of Fig. 2 and Fig. 4 is a verticalsectional view takensubstanti'ally on the line 1-1 of; Fig.3.

In said drawing, denotes the body bolster and 11 the truck bolster of arailway car which may be of any well known or desirable constructionpivotally connected at the center in the usual manner. As shown, thebody bolster is provided with integral thrust or bearing plates 12 andthe truck bolster has secured thereto my improved roller bearingdesignated generally by the reference A.

Each bearing member A, as shown, preferably comprises a base plate orcasting 40 13 having laterally extended flanges 14 by which the same issecured to the truck bolster by rivets or other suitable fasteningdevices. Near each end, the base casting is provided with integral,upwardly extending brackets 15 each of which is provided with anangularly disposed slot or recess 16 open at the top thereof asindicated at 17 the bottoms of said recesses 16 being curved asindicated at 18 to provide a bearing for trunnions 19 formed on theopposite sides of a cradle 20, said trunnions being preferably formedintegrally with said cradle. As clearly shown in the drawing, the axisof the trunnions 19, 19 extends transversely of the 55 truck bolster.Midway between the trunnions IQla-nd on opposite sides of the cradle,the latter is tending hollow'integr'al bearings 21 on. each. of which isdetachably mounted a sleeve 22 the' latter in turn supportingdetachable. antifriction rollers 23, the rollers and sleeves 22' beingheld" in place by washers 2 1-, 24 mounted on a bolt 25'- the latterhaving? a. h'ead26 at on'e'end thereof and a nut 27 at the other-end,thenut b'eingli'eld'in position by a cotter 28, it. being. understoodthat the bolt 25 extends entirely through the cradle 20' as shown mostclearl'yfin Fig. 3'. Extending upwardly from the center of the baseplate 13 is a leaf springf29 the upper endof which engages in a flarednotch 30 formed on the under side of the cradle 20.

In assembling. my improved bearing membe'ri A, the cradle 20 is firstplacedi'n position with the trunnions 1'9, 19 in the inclined recesses16 and atthe'same'time the spring 9,9 is engaged in the flared notch 30.Aftertle cradle has thus been placed in position, the sleeves 22 androllers 23' are applied and the same prevented from falling off by thebolt and washers, previously described. In this connection it will benoted that there is a certain amount of clearance between the lowerinner edges of the rollers 23 and the edges of the upstanding lugs orbrackets 15, 15 whereby the cradle and rollers carried thereby arepermitted sufficient oscillating or rocking movement to accommodatethemselves to the positions of the bolsters. At the same time it will benoted that the cradle 20 can not be removed from the base casting solong as the rollers 23 are in position since the latter overlap theupstanding lugs or brackets 15, as clearly shown in Fig. 4, whichprevents'the trunv nions 19 from being moved laterally or horizontallysuflici'ently for the sameto be disengaged from the recesses 16, 16.

From the preceding description it will be seen that the roller bearingwhich I have provided is of relatively cheap construction; most of theparts may be made in the form of castings; the parts may be readilyassembled and disassembled; and automatically operating means areprovided for returning the rollers and cradle by which they are carriedto normal position.

I am aware that numerous changes may be made in the details ofconstruction and arrangements of parts and I do not wish to providedwith oppositely ex- I be confined to the structure herein described indetail.

I claim 1. In a side bearing for railway cars, the combination with arockablymounted cradle having oppositely extending journals formedintegrally therewith, of rollers detachably mounted on said journals.

2. In a side bearing for railway cars, the combination with a basecasting adapted to be secured to a bolster, of a cradle rockably mountedon said casting about an axis extending transversely of the bolster, andautomatically operating means for returning. v said cradle to normalposition.

3. In a side bearing for railway cars, the combination with a base platehaving bearings therein, of a cradle having laterally extendedtrunnions, the trunnions being removably mounted in said bearings, androllers carried by said cradle, said rollers preventing disengagement ofthe cradle from the base plate.

4. In a side bearing for railway cars, the combination with a baseplate, of a cradle rockably mounted on said base plate, a pair ofaxially alined rollerscarried by said cradle, and a spring extendingbetween said plate and the cradle for returning the latter to normalposition.

5. In a side bearing for railway cars, the combination with a base platehaving spaced lugs extending therefrom, said lugs having recessesinclined relatively to the base casting and formed on the'inner sides ofsaid lugs, each of said recesses being openat one end and curved at theother end to thereby form bearings, of a cradle having oppositelyextending trunnions, and anti-frictionmeans earned by sald cradle, sa1dtrunnions being inserted into said recesses before said meansareattached to the cradle, said means, when in place, engaging said lugsand thereby preventing acc idental disengagement of the cradle from thebase plate.

6. In a side bearing for railway cars, the.

curved at the lower ends to thereby provide bearings, of a cradle havingdiametrically disposed trunnions insertible in said recesses through theopen ends thereof and rollers carried by said cradle on the oppositesides thereof, said rollers preventing the removal of the cradletrunnions from said recesses.

7. In a side bearing for railway cars, the combination with a baseplate, of a cradle, means for rockably connecting the cradle to the baseplate, said meansincluding recesses formed on one of said members andlateral projections extending into said recesses formed on the other ofsaid members, alined rollers carried by saidcradle, and spring means forcentering said cradle.
